Problems solved by technology

The configuration of each SRS resource set can only support a periodic or aperiodic configuration behavior, and cannot achieve a combination of periodic and aperiodic transmission methods.
In addition, the existing protocol has two separate processes for the channel detection or channel information acquisition of the uplink and downlink channels. In theory, two sets of SRS need to be configured to obtain the respective channel information, and the overhead is relatively large.

example 1

[0252] The base station configures the SRS resource set set#1, whose usage (usage) is used for antenna switching (antenna switching), so that it can be used for acquiring downlink channel information. The base station further indicates that some resources or ports in set#1 can be used for uplink service transmission, such as codebook-based uplink data transmission, such as resource 1.1 and / or port 1.1.

[0253] When the base station instructs the terminal to perform uplink data transmission through the DCI, the resource 1.1 and / or port 1.1 may be directly indicated, and the terminal performs uplink service transmission according to the SRS resource 1.1 and / or port 1.1.

example 2

[0255] The base station configures the SRS resource set set#1, and the usage is used for antenna switching (antenna switching) to acquire downlink channel information. The base station further indicates that some of the resources or ports can be used for uplink service transmission, such as codebook-based uplink data transmission, such as resource 1.1 or port 1.1.

[0256] The base station configures resources or resource set #2 for uplink codebook-based data transmission, and the resource or resource set may be aperiodic transmission. In addition, the resource 1.1 or port 1.1 may also be configured as a reference signal or a port of a spatial relationship for the resource. The power control parameter configuration of this resource is the same as resource or port 1.1.

[0257] When the base station instructs the terminal to perform uplink data transmission through the DCI, it may indicate the resources of set#2, and may further indicate that the resources in set#2 are used fo...

example 3

[0263] The base station configures the SRS resource set set#1, and the usage is used for antenna switching (antenna switching) to acquire downlink channel information. The base station further indicates that some of the resources or ports can be used for uplink service transmission, such as codebook-based uplink data transmission, such as resources or ports 1.1 and 1.2.

[0264] The base station configures resources or resource set #3 for downlink transmission, such as antenna switching, and further indicates that the resources or ports in it can be used for uplink service transmission, such as codebook-based uplink transmission, where the ports or resources are 3.1, 3.2 or port 3.1, 3.2. For the corresponding resource and port spatial relationship, the reference signal can be configured as 1.1 or 1.2 of the SRS resource or port. The configured power control parameters need to be the same as the above SRS resources.

[0265] When the base station instructs the terminal to pe...

Abstract

A resource allocation method, a terminal and a base station, the method comprising: the base station allocates a first resource for antenna switching for the terminal, and allocates or indicates a resource and / or port available for uplink transmission in the first resource, the first resource being at least one sounding reference signal (SRS) resource or an SRS resource set. According to the resource configuration method, the terminal and the base station provided by the embodiment of the invention, the base station can obtain the downlink channel information by using the sending of the SRS, and the base station can be assisted to obtain the uplink channel information. Besides, the embodiment of the invention can realize the joint transmission of the periodic SRS and the aperiodic SRS without increasing the SRS resources, and achieves the purposes of reducing the SRS transmission resources and supporting a better acquisition mode of the channel information combining the periodic SRS and the aperiodic SRS at the same time.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a resource allocation method, a terminal and a base station. Background technique [0002] Currently, uplink transmission based on a codebook can only support one Sounding Reference Signal (SRS) resource set (set), and each resource set can only have one type of time behavior, for example, period or aperiodic. However, only supporting periodic or aperiodic transmission is not the optimal working method for the system. The analysis of the advantages and disadvantages of only supporting periodic or aperiodic working methods is as follows: [0003] For periodic configuration, it can ensure that the base station always obtains uplink channel information and performs scheduling, but it lacks flexibility, and it is difficult to obtain accurate channel information between two transmissions, which cannot meet the business needs that come at any time. If the cycle d...
